HOSE-COUPLING.

SPECIFICATION forming part of Letters Patent No. 774,196, dated November8, 1904:.

Application filed May 17, 1904. Serial No. 208,428- (NO 11101181.)

To all whom, it may concern.-

Beit known that I, Aueus'r W. NUNN, a citi- Zen of the United States,residing at Rochester, in the county of Monroe and State of New York,have invented certain new and useful Improvements in Hose-Couplings; andI do declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

This invention relates to new and useful improvements in hose-couplers;and the object of the invention is to produce a device whereby couplingsof various sizes may be connected together without threaded connections,thereby rendering it possible to easily and quickly connect differentmakes of hose-pipes for emergency or other purposes.

My invention consists in various details of construction andcombinations and arrangements of parts, which will be hereinafter fully'described and then specifically defined in the appended claims.

My invention is illustrated in the accompanying drawings, which, withthe letters of reference marked thereon, form a part of thisapplication. and in which- Figure 1 is an elevation showing two pipesconnected together by my improved hosecoupling, and Fig. 2 is a verticallongitudinal section through the ends coupled together.

Reference now being had to the details of the drawings by letter, Adesignates a coupling adapted to be secured to a hydrant-plug and hasinterior threads A and oppositelydisposed lugs B for attachment to aspanner, and projecting from the coupling A is a cylindrical shankportion O, having exterior circumferential threads O extending a portionof its length and a plain unthreaded portion D beyond the threadedportion adjacent to the free end of said cylindrical portion. Mountedupon the threaded circumference of the cylindrical portion O is a ringE, having a central aperture the walls of which are threaded conformingto the threads O, and E designates oppositely-disposed lugs forengagement with a spanner.

F designates a ring having an annular recess F about its circumference,adjacent to one edge thereof, which is adapted to receive a flanged orcircular ring G, which is integral with or secured to one edge of thering E, as shown in the sectional view of the drawings. One face of saidring E is recessed out, as at e, to receive the end of the ring Fintermediate said recess F and the adjacent edge of the ring, and whenso positioned the flange or ring G is disposed in the recess F, therebyswiveling the two rings E and F together. Projecting from the ring E atpositions diametrically opposite are the hooks K, which are adapted toengage the diametrically opposite lugs N upon the end of a hose-couplingwhich is to be connected to the cylindrical portion O. Said lugs Nproject from the threaded coupling N, which is the common constructionof fire-hose coupling, provided with a suitable gasket or washer O. Incoupling the ends of two sections of hose the portion of the cylinder Obeyond the threads is adapted to be inserted instead of the coupling Nin the manner shown in the sectional view of the drawings, and the endof the cylindrical portion O is adapted to contact with the washer orgasket O, which rests against the shoulder O on the coupler N, and inorder to hold said cylindrical portion against the gasket thecoupling-ring F is turned so that the hooks K will engage said lugs Nupon the coupler N, and afterward the ring E is turned toward thecoupler-head A, which will draw the swivelecl ring Fand also the couplerN engaged thereby tightly against the end of the cylindrical portion Oof the coupler A, thereby affording a secure and water-tight joint.

By the provision of a coupler embodying the features of my invention itwill be noted that a simple and eflicient means is provided forattaching hose which may be of different sizes and regardless of thedifferent kinds of threads upon the coupling ends.

While I have shown a particular detailed construction of apparatusembodying the features of my invention, it will be understood that I mayvary the same, if desired, as to details without in any way departingfrom the spirit of the invention.

While my invention is intended more particularly for use in makinghydrant connections, it will be at once evident that it is also adaptedfor connecting together sections of hose, and it is also evident thatthe parts may be made reverse from those shown in the drawings.

Having thus fully described my invention, what 1 claim as new, anddesire to secure by Letters Patent, is

1. A hose-coupling comprising a hydrant connection having a contractedbarrel portion, a portion of the circumference of which is threaded, acoupling-ring with interior threads mounted upon the threaded portion ofthe hydrant-coupling, a coupling-ring swiveled to said threaded ring, ahose-coupling with lugs diametrically opposite and adapted to be engagedby said hooks, a gasket seated on the shoulder on the inner face of saidhose-coupling, and against which the barrel portion of thehydrant-coupling is adapted to contact, as set forth.

2. A hose-coupling comprising a hydrant connection having a contractedbarrel portion, threaded about a portion of its circumference, athreaded ring fitted to said barrel portion and having diametricallyopposite lugs, one face of said threaded ring being recessed, a ring Gsecured to the face of said threaded ring, the inner marginal edge ofsaid ring G projecting over said recessed portion, a coupling-ring heldin said recess by the ring G, and having diametrically opposite hooks, ahose-couplin g with lugs diametrically opposite adapted to be engaged bysaid hooks, a gasket seated against the shoulder of said hose-couplingand against which the end of said barrel is adapted to contact, as setforth.

In testimony whereof I hereunto affix my signature in presence of twoWitnesses.

AUGUST W. NUNN.
